Which brand of oil

[HDVROD100]

I just bought a '90 Stratos 285, with a Johnson GT150. The previous owner has removed most of the oil injection parts, so I have to mix the oil in the gas. What type / brand of oil should I use? I heard Quick Silver was made for Mercs / Mariners, but would it be safe to use in my boat, or should I stick with the Evinrude / Johnson oil?
Thanks,
John

XD 50 will be fine or XD 100 if you want to spend the extra money. Both BRP oils for Evinrude
